SNOW PLOW.

SPECIFICATION forming part of Letters Patent No. 395,548, dated January1, 1889.

Application filed February 13, 1888. Serial No. 263,761 (No model.)

T (ZZZ 1117mm it may concern.-

Be it known that I, JOSEPH CORBET'J, of the city, county, and State ofNew York, have invented a new and Improved Snow-Plow, of

which the following is a full, clear, and exact description.

This invention relates to snow-plows of the class wherein a revolubleblade-carrying hub or head is employed to gather and subse- IO quentlythrow the snow to one side of the path of the plow, the main object ofthe invention being to provide for the positive rotation of theblade-carrying hub or head irrespective of the movement of theplow-carriage; but other objects are aimed at and secured by theconstruction illustrated in the drawings, and hereinafter specificallydescribed.

Reference is to be had to the accompanying 2o drawings, forming a partof this specification, in which similar ligurcs of reference indicatecorresponding parts in all the views.

Figure 1 is a plan view of the plow. Fig. 2 is a side view of the same.Fig. 3 is an enlarged sectional detail view of the powerwheel, the viewbeing taken on line of Fig. 2. Fig. 4 is an enlarged view of theplowcarriage, the hood, case, and the hub or head being shown in sectionon line y y of Fig. 2. Fig. 5 is a front View of the plow, and Fig. 6

is a sectional elevation on line .2 .2 of Fig. 1.

The mechanism of the plow illustrated in the drawings above referred tois supported by a frame made up of side bars, 10, a rear crossbar, 11,arms 12 and 13, which extend, respectively, upward and downward from theforward ends of the side bars, a hoop, 14, that is supported by the arms12 and 13, and a U- shaped bracket, 15, which projects forward somewhatbeyond the hoop 14. This frame is mounted on wheels 10, the journals ofwhich are secured to the side bars, 10.

To the hoop 14 there is secured a metallic sheathing, 17, which isprovided with a flaring hood, 18, the lower edge of which is sup portedby an inwardly-curved cross-bar, 19, that is connected to runners 20,which said runners are in turn connected to the hoop 14 by bars 21, thearrangement being such that When the runners rest upon the sidewalk orother place over which the plow is being operated the lower forwardedge, a, of the hood 18 will closely approach said sidewalk.

The hood 18 is not connected directly to the case or sheathing 17, butis connected to a flange, '2 that is secured to the forward edge of thecasing, this flange forming a housing, within which the oierating-headrevolves, as will be hereinafter more fully explained.

As before stated, the bar 15) is inwardly 6o curved, the general curveof the bar, however, being broken at the center, at which point the baris U-shaped, this construction providing for a free space just below theforward end of the cutter-head. The lower portion of the flange iiscutaway, as shown in the drawings, thus providing for the free entranceof snow, as will be readily understood.

A horizontal shaft, 23, is mounted in bearings formed in the cross-bar11 and the bracket 15, and this shaft carries a sleeve, 24, that isformed with a bevel-faced flange, 25, to which there is riveted orotherwise secured a con e-shaped head, so, that is provided with avertical annular flange, 27, which said flange closely approaches theinner face of the case formed by the sheathing 17, the flange beingarranged just in advance of the hoop 14.

To the outer face of the cone-shaped head 26 there is secured a seriesof radially-extending blades, 28, the forward edges of which are curvedover to one side, said edges, however, being inclined to the rear fromthe forward end of the head, while the outer edges, Z), of the bladesare substantially parallel. with the shaft 23 and closely approach theinner face of the case 17. The extreme forward end of the sleeve 24 istopped to receive the threaded shank of a bolt, 29, the head of which isconi- 0 cal and forms the apex of the head 26.

In the case 17 there are two openings, 2 and 3, over which there areplaced hoods 30 and 31, and in connection with these openings there isarranged a cover, 32, which slides in 5 ways upon the outside of thecase 17, and which maybe moved to the position shown in Fig. 6 to closethe opening 3, or which may be lowered to close the opening 2, as willbe readily understood. I oo The machine shown in the drawings isdesigned to be used as a hand machine, and is provided with tworearwardly and upwardly extending bars, 34:, that are pivotallyconnected to the side bars, 10, just in advance of the wheel-journals,these bars carrying a breast-piece, 35,'to which, if desired, there maybe secured a plate, 36.

To the lower end of one of the bars ill, I secure a segmental rack, 37,that is engaged by a weighted pawl, 38, said pawl being pivotallyconnected to the adjacent side bar, 10, the arrangement being such thatthe bars 34: maybe moved and held at any angle desired, thus providingfor an adjustment suitable for the user of the machine. The bars 3i arestrengthened and braced by cross-pieces 3.), placed at intervalsthroughout the length of the bars, and at a point near the upper ends ofthe bars there is journaled a shaft, 4L0, wh ich is provided with twocrank-hamlles, t].

The shaft 40 carries a chain or sprocket wheel, -t2, upon either side ofwhich there is a guard-rim, 43, said rims being upheld by shortcross-rods 44, that are carried by the rim of the wheel 42. Adriving-chain, 45, passes about the wheel 42, and also about a smallchain or sprocket wheel, 46, that is mounted 011 a short transverseshaft, 4:7, one end of which is journaled in one of the cross-bars 10,while the other end is journaled in abracket, 48, which extends forwardfrom the cross-bar 11, the chain being held from displacement on oneside by a disk, 49, and on the other by a large bevel-gear, 50, whichdisk and gear are mounted on the shaft 47. Th e gear engages a smallergear or pinion, 5 'I, that is carried by the shaft 23, so that when arotary movement is imparted to the shaft 40 such motion will betransmitted to the shaft 47, and through the medium of the gears 50 and51 to the shaft 23 and the parts carried thereby.

In order that the operator may be free to use both hands upon thecrank-handles of the shaft 40, I provide the breast-piece with studs orbuttons 52, to which, buttons there is connected a neck-strap, 53.

In addition to the blades 28, the head 26 is provided with a number ofshort blades, 54, which extend from the outer edge of the flange 27 toapoint about halfway up the face of the head 26.

In operating the machine above described the neck-strap 53 is placedover the shoulders of the user, the handles of the crank-arms 41 aregrasped ,the machine is forced forward,and the crank-shaft 40 revolvedin order that a rapid rotary movement may be imparted to the head 26,which head in revolving will gather up the snow. After the snow has beengathered by the blades, as above set forth, it is thrown out of the casethrough one of the openings formed therein, the opening 2 delivering thesnow to the left and the opening 3 to the right of the machine. Thisthrowing out of the snow is brought about by the centrifugal forceproduced by the rapid rotation of the head 26.

By providing the short blades 54:, I secure amore uniform action and atthe same time economize power; but it would not be advisable to continuethese blades 54 to the apex of the head 26, as the snow would then tendto clog between the blades.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a snow-plow, a revoluble head provided with aseries of blades, 26, and a sec ond series of short blades, 5i,substantially as described.

2. In a snow-plow, a conical revoluble head provided with a series ofblades, 26, and a second series of short blades, 54, substantially asdescribed.

3. In a snow-plow, the combination, with a supporting frame, ofcarrierwheels upon which the frame is mounted, handle-bars pi votallyconnected to the frame, a rack formed at the lower end of one of thebars, and a weighted pawl pivotally connected to the frame and arrangedto engage the rack, as and for the purpose stated.

4-. In a snow-plow, the combination, with a main frame, of an aperturedcase carried thereby and formed with a f0rwardly-extending hood, runnersby which the hood is supported, a conical head mounted within the caseand upon a horizontal shaft, blades carried by the head, a gear carriedby the horizontal shaft, a transverse shaft, a gear and sprocket wheelcarried thereby, the gear of the transverse shaft'en gaging the gear ofthe horizontal shaft, a crank-shaft carrying a sprocket-wheel, and adrive-chain running-in engagement with the two s 'n'ocketwheels,substantially as described.

5. In a snow-plow, the combination, with a blade-carrying head and ameans for revolving the head, of a case surrounding the head, and aflange, 'z', the ,lower portion of which is cut away, said flange beingconnected to the forward edge of the case, substantially as described.

6. In a snow-plow, the combination, with a revoluble blade-carryinghead, of an openfaced case provided with hooded openings, one at theside and one at the top of the case, and a cover or slide arranged toclose either of said openin and open the other, substantially as setforth.
